Properly Installing Slip Joint Washers in Your Plumbing System

When PVC is used to establish plumbing connections, you will run across slip joints. Slip joints allow a raw pipe end to slide smoothly into the threaded part of a fitting. Ends are connected, and then sealed using both a slip joint washer and a slip nut. The former has a tapered and flat end. When you install it yourself, without the help of a plumber, the slip nut will compress the slip joint washer to seal the connection against leaks.

1. Get ready the pipes which should be connected by cutting them to length. Afterwards, remove the burrs from the cut end and clean the pipe end of any sort of debris using a dry and clean rag.

2. Slide a couple of slip joint nuts to the raw portion of the PVC pipe. The first slip joint nut threads should face the flanged portion of the pipe as well as the other slip joint nut’s threads that are facing the raw pipe end.

3. The slip joint nut should then be pushed down the pipe, and the slip joint washer slid onto the raw portion of the pipe. When doing the latter, make sure that the tapered portion of the washer faces the slip joint nut. Have the washer slid an inch and a half down the pipe so it is kept away from the end which will slide down the threaded section of the fitting.

4. The raw portion of the pipe should then be inserted to the threaded part of the fitting.

5. Get the slip joint nut tightened on the flanged pipe portion before sliding its washer down the fitting threads. The flat portion of the washer needs to sit well against the threads of the fitting.

6. Slide the nut of the slip joint down the washer for the same part before turning the nut to the left so that the nut is secured to the fitting and to compress the washer of the slip joint.

7. Repeat the process for every slip joint connection.

8. Switch the water on and check all slip joint connections for any leaks on it. If a connection becomes leaky, you should first check and tighten the slip joint nut. Take this part out if water still leaks to ensure that the accompanying washer was not installed with its tapered end facing towards the fitting threads.
